/* ** ** Swift/XRT hardness ratio for Mrk 501. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 54946.075265 0.000341 0.29276 0.04820 0.97458 0 3.42932 0.26432 2.93625 0.22632 1.00396 0.14606 0.85923 0.12498 54946.075916 0.000310 0.33687 0.05586 0.98131 0 3.23685 0.27048 2.79934 0.23392 1.09039 0.15619 0.94331 0.13512 54946.076529 0.000304 0.33563 0.05462 0.98095 0 3.44249 0.28030 2.93956 0.23935 1.15539 0.16282 0.98651 0.13901 54946.077233 0.000399 0.24517 0.03966 0.97826 0 3.47286 0.24794 2.96498 0.21168 0.85144 0.12358 0.72539 0.10526 54946.078014 0.000382 0.26379 0.04152 0.96970 0 3.53039 0.25378 3.02109 0.21714 0.93129 0.13042 0.79820 0.11177 54946.078867 0.000472 0.21291 0.03378 0.98773 0 3.38947 0.22438 2.88384 0.19090 0.72164 0.10404 0.61172 0.08819 54946.079712 0.000373 0.25019 0.03975 0.97674 0 3.65843 0.25839 3.15967 0.22316 0.91531 0.13027 0.79053 0.11251 54946.080433 0.000347 0.24759 0.03959 0.97500 0 3.97085 0.28196 3.42069 0.24290 0.98314 0.14087 0.84656 0.12126 54946.081130 0.000350 0.30069 0.04941 0.98347 0 3.21517 0.25325 2.74951 0.21655 0.96676 0.13941 0.82762 0.11932 54946.081799 0.000318 0.27838 0.04454 0.97273 0 3.93150 0.29424 3.35825 0.25131 1.09446 0.15479 0.93614 0.13239 54946.082820 0.000703 0.33029 0.03534 0.99177 0 3.47312 0.18518 2.97641 0.15868 1.14713 0.10641 0.98357 0.09124 54946.083870 0.000347 0.30042 0.04935 0.99167 0 3.23962 0.25490 2.76164 0.21726 0.97326 0.14034 0.82762 0.11932 54946.084582 0.000365 0.25281 0.03998 0.97619 0 3.73917 0.26476 3.21947 0.22796 0.94530 0.13369 0.81436 0.11517 54946.085427 0.000480 0.21707 0.03392 0.97590 0 3.36768 0.22106 2.88334 0.18926 0.73101 0.10366 0.62377 0.08845 54946.086211 0.000304 0.30173 0.04893 0.96190 0 3.78023 0.29378 3.26843 0.25400 1.14060 0.16234 0.98621 0.14036 54946.086888 0.000367 0.25867 0.04158 0.98425 0 3.54240 0.25847 3.06321 0.22351 0.91632 0.13126 0.79238 0.11350 54946.087710 0.000454 0.29574 0.04190 0.98089 0 3.35136 0.22636 2.89794 0.19574 0.99113 0.12343 0.85704 0.10673
